SPAM is one of the goals that must be achieved; where the government through PERUMDA Tirta Sukapura Sukaraja Unit, uses raw water sources from the Ciwulan River for services in the Sukaraja District area. As part of the achievement, where the success of clean water services is highly dependent on quantity and quality. The results of the calculation of water demand were obtained through statistical tests and obtained an average water usage of 112,92 liters per second, with a water demand up to 2045 of 88,24 liters per second. The raw water discharge reliability test is analyzed through a theoretical distribution test to obtain an available supply for domestic activities of 200 liters per second based on the distribution selected: Log Normal. In addition, quality analysis was carried out by assessing the status of water quality for three water quality index methods, including STORET, Pollution Index, and NSF-WQI, where the raw water of the Ciwulan River is included in the index criteria for good to medium pollution. The corellation between discharge and water quality parameters produces a negative corellation for TDS, Amonia, and Nitrate with the condition that the higher the discharge, the lower the concentration value of the water quality parameters, which can occur due to a natural decomposition process. Meanwhile, a positive relationship was obtained for Total Coliform analysis, with the condition that the higher the discharge, the higher the concentration value of water quality parameters.
